I was replacing the vacuum reserve hose where it goes into the T behind the plenum when I broke the hard plastic 3 way thing,what do those other 2 hoses go to?The car drove fine even without thin hard plastic hose on the left side it looks like it goes in to the firewall.Just wanted to know what that 3 way thing is called so I know what to ask for at NAPA.Thanks

 

The three way thing is called a vacuum hose T.
